Abstract: In conventional thermoelectric conversion modules, P-type and N-type thermoelectric semiconductor chips are alternately arranged in both the longitudinal and the transverse directions. Consequently, assembling work is complicated and there arises the problem in quality that erroneous types of chips are arranged. In the present invention, therefore, rows or columns of chips are constituted by thermoelectric semiconductor chips (4, 5) of the same type, to improve the assembling workability as well as to prevent erroneous arrangements. As a preferred fabricating method, bar-shaped thermoelectric semiconductors are used and are joined to one substrate (1) and then are electrically disconnected (8) between leads (2) to form the individual chips.
